You will need a pie pan lined with pie pastry to begin. Use fruit of your own choosing.
2 cups warm milk
1/2 to 1 cup sugar, depending on the sweetness of the fruit
1/3 teaspoon salt
1 Tablespoon flour (or 2 T cornstarch)
1 teaspoon vanilla
dash of nutmeg
Put just enough fruit (drained) to cover bottom of pan. Pour custard mixture over fruit. Bake at 375 degrees for 15 minutes and then switch to 325 degrees and bake for additional 35 minutes.
